Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing tamper-evident and child-safety packaging containers fail to effectively combine both features, leading to potential tampering and accessibility issues for individuals with disabilities or infirmities, while also being costly and limited to manufacturer-level application.

Innovation Solution

A tamper-evident and child-safety packaging design featuring a cap with a tamper-evident tab and a press-tab on the side wall, allowing secure closure and visual indication of tampering, suitable for use by pharmacists and consumers, and compatible with standard fasteners.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If existing tamper-evident packaging uses shrink-bands or labels, then tamper-evident requirement is met, but child safety factor is neglected

Engineering Contradiction:

Improvetamper-evident indicationVSAvoidchild accessibility

Core Design Contradiction:

ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The patent combines tamper-evident and child-safety features into a single integrated cap system. The cap includes both a tamper-evident tab that indicates if the cap has been removed or opened, and child-safety mechanisms requiring coordinated pressing and rotating actions to open, thereby simultaneously addressing both tamper-evident and child-safety requirements.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The cap is divided into functional segments: an outer cap portion with tamper-evident tab, an inner cap portion with child-safety features including press tabs and rotational locking mechanisms. This segmentation allows each component to independently fulfill its specific function while working together as a unified system.

Inventive Principle:

Principle #1Segmentation

2Object-affected harmful factors

If child safety caps require pressing hard and rotating simultaneously, then child safety is improved, but ease of operation for older people and patients deteriorates

Engineering Contradiction:

Improvechild accessibilityVSAvoidoperation for infirm individuals

Core Design Contradiction:

Object-affected harmful factorsVSEase of operation

Solution Approach 1:

The cap incorporates a resilient press tab that dynamically responds to user input. The press tab can be easily depressed by children or infirm individuals due to its spring-loaded design, and this depression action triggers the opening mechanism without requiring excessive force or complex coordinated movements.

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

Instead of requiring users to press hard and rotate simultaneously as in traditional child-safety caps, this invention inverts the sequence: the press tab is first depressed to release the locking mechanism, allowing the cap to be opened by simple rotation without requiring hard pressing. This reverses the traditional approach to improve ease of operation.

Inventive Principle:

Principle #13The other way round (Inversion)

3Reliability

If manufacturer-level tamper-evident application is used, then tamper evidence is ensured, but capital expenditure and manufacturing complexity increase

Engineering Contradiction:

Improvetamper evidenceVSAvoidmanufacturing cost and complexity

Core Design Contradiction:

ReliabilityVSEase of manufacture

Solution Approach 1:

The tamper-evident cap is designed to be self-applied by pharmacists or dispensers without requiring specialized manufacturer equipment. The cap includes built-in features such as the tamper-evident tab and sealing mechanisms that automatically provide tamper evidence when properly installed, eliminating the need for costly manufacturer-level application processes.

Inventive Principle:

Principle #25Self-service

Solution Approach 2:

The cap uses inexpensive, disposable components such as the tamper-evident tab and sealing elements that can be easily manufactured and applied. These single-use components provide reliable tamper evidence without requiring expensive reusable equipment or complex manufacturing processes.

Inventive Principle:

Principle #27Cheap short-living objects (Disposable)

AI summary

This invention is for a safety child-resistant and tamper-evident packaging container cap having a tamper-evident tab on the top of the cap and a press-tab on the side wall that provides both tamper-evident and child safety features to warn and protect consumers as well as dispensers such as: pharmacists, hospitals, medical centers, and manufacturers that the containers have not been opened and the number of pills contained in the container is accurate. The uniqueness of the cap allows the pharmacist and medical staffs or provider to close it by turning it clockwise, while the patient turns the cap counterclockwise to open it. However, this process will break off the tamper-evident disc away from the outside cap, which indicates tampering and exposes the upper surface of the inner lid, wherein the additional marking displays “OPENED” to warn of tampering.
